SHAKING-MACHINE. FOR MOVEMENT CURE.

SPECIFICATIOH forming part of Letters Patent No. 433,011, dated July 29, 1890.

Application filed March 31, 1890. Serial No. 346.051. (ModeL) Patented in Sweden October 2, 1889, No. 2,206, and in Norway October 7,1889,No.1,455.

To all whom, it may concern.-

Be itknown that LCARL HARALD LIEDBECK, a subject of the King of Sweden, and a resident of Stockholm, Sweden, have invented a Universal Shaking-Machine for the Movement Cure, (for which I have obtained a Swedish patent, No. 2,206, dated October 2, 1889, and a Norwegian patent, No. 1,455, dated October 7, 1889,) of which the following is a specification.

lhis invention relates to a machine for imparting a shaking motion to some part of the body, which motion constitutes, as known, one of the most important forms of motion in the movement cure. Manual labor to impart this shaking motion is too tedious and fatiguing, too uncertain and irregular, and will not afford a uniform shaking for more than a minute or two, and cannot give the required speed to the apparatus. For these and. many other apparent reasons it is of great importance to impart the motions by a machine, whereby any degree of rapidity and a steady uniformity of movement may be attained at will, and as may be needed or desired. \Vith my invention but little space is required for the apparatus, and it is adapted for use in families and houses, and is so constructed that the shaking motion may be imparted to just that part ,of the body needing treatment without requiring the patient to place hisbodyin any particular position. My invention thus has an almost unlimited or universal application to any part of the person.

The machine consists of three principal parts: the driving mechanism, the shaking apparatus, and the parts of contact.

In the annexed drawings, Figure 1 shows an elevation of the driving mechanism; Fig. 1, a transverse section in the line 1 2 of Fig. 1; Fig. 1", a detailcross-scction; Fig. 2, a crossscction of the shaking apparatus in the line E F of Fig. 2, with the shaking part in the same plane the cam or eccentric and surrounding it; Fig. 2, a central longitudinal section of the shaker, cam-shaft, and handle; Fig. 2",a cross-section in the line G11 of Fig. 2; Fig. 2, an end view of Fig. 2; Fig. 3, a central longitudinal. section of the shaking apparatus with the suspension-shaft of the shaking part below the cam or concentric;

Figs. 3, 3", and 3 cross-sections, respectively, in the lines J K, L M, and N O of Fig. 3; Fig. 4:, an elevation and a vertical section of a shaking apparatus with the suspensionshaft of the shaking part above the cam; Figs. 4 and 4*, cross-sections, respectively, in the lines A B and C D of Fig. at; and Fig. 5, two sectional views, taken at right angles to each other, of a shaking apparatus substantially like that one represented. by Fig. 4, but wit-h the cam as well as the shaking part located in the longitudinal direction of the shaft in lieu of being perpendicular to the same.

The driving mechanism is supported by a clamping-frame a, in the lower part of which is an attachment screw, by means of which it may be located and secured at a suitable place-for instance, upon a table. In the top of the frame runs a horizontal shaft Z), at its free end supporting a crank or a flywheel 0, provided with a crank. On theshaft b is fixed a toothed wheel (Z, gearing with one or more driving-wheels c, fixed on shafts e, running in the frame, from which shafts the r0- tatory motion produced by turning the crank may be transmitted to the shaking apparatus, held in the hand by means of a flexible shaft, (not necessary to be shown,) the one end of which is connected with the drivingshaft of a shaking apparatus, while its other end is connected with the shaft 6. By means of a suitably-adapted relation of size between the toothed wheel and the driving-wheels any desired speed may be imparted to the driving-shaft, and thus also to the shaking motion, which speed, besides, may, during the very motion, be increased or diminished by modifying the speed by which the crank is turned.

The shaking apparatus is partly or wholly inclosed in a handle, which is held in the hand when the apparatus is to be used. Through this handle runs a driving-shaft g, inclosed in a tube f, one end f of which shaft being, by means of the flexible shaft above named, connected with the driving mechan ism. The other end of the driving-shaft g supports a cam (or an eccentric) 7L, prefer ably triangular and fixed at right angles to the shaft, as shown in Figs. 2, 2*, 3, and 3, and which, when rotating, produces the shaking motion by acting on the side walls of the part K. It will be evident that the relations of the cam and the shell or shaker part K may be varied at will to give a greater or less shake, or the shaft and its cam may have their relations changed for the same purpose, or the shaft may be located perpendicular to the handle, as shown in Fig. 5.

The most simple form of the shaking apparatus is represented in Fig. 2, where the eccentric h is inclosed between both the sliding surfaces of a capsule k, to which, at the rotation of the eccentric, an alternate motion is imparted on a subjacent plane Z.

The capsule is covered with a lid m, with which the part of contact suitable for the occasion is connected. If it is desired that the shaking part shall move around a shaft located below the eccentric, as shown in Fig. 3, the cap sule 7c is prolonged downward and is by means of pivots '00 connected at the bottom with the tube f, surrounding the driving-shaft. The top of the tube is then provided with a shoulder or collar g, which, running between two guiding-planes adapted in the capsule, is guiding the shaking part at its oscillating motion, which is created at the rotation of the eccentric between the sliding surfaces of the capsule. The capsule even in this case is covered with a lid, on which for every particular event a suitable part of contact may be adapted. If, on the contrary, itis desired that the shaking part shall move around a shaft locatedabove the eccentric, as shown in Fig. t, the end of the tube f, which is located under the eccentric, should be provided with a threaded rib or swelling or, constituting an attachment to the hollow handle,which consists of two parts, which are screwed on from diiferent sides. This swelling has two arms 1 located on the respective sides of the eccentric, which arms sustain the suspensionshaft of the shaking part, constituting at the same time a guiding-plane for the lower part of the shaker, surrounding the eccentric; which part, in the manner already described, is put in a shaking motion by the rotation of the cam.

I11 Fig. 5 the driving-shaft g is shown as placed perpendicular to the handle, which incloses its one end, supporting the eccentric h. This is inclosed by the lower frame-shaped part of the shaker, which is suspended on a shaft 0, and in the manner described above connected with a device 7" for supporting the part to be placed in contact with the person. The shaking part can be connected with the contact-piece in such a way that its top part, as indicated in Fig. 4, is made tubular and threaded at the interior, as shown, so that a pin or spindle may be screwed in, the contact-piece being fixed on" its free end. By means of this arrangement it is possible, while the machine is in use and the contact piece or part r is pressed against the body, to change the length of the shaking part-that is to say, the extent or amplitude of the shaking-Joy turning the machine-handle so as to screw the pin in or out. The contact-piece r, Fig. 4., may have such a shape as is most suitable to the part of the body which is to be treated. They may thus be disk-shaped, cylindric, bowl-shaped, conical, or fork-shaped, &c., and have a handle, which, according to the shape of the top part of the shaker, is disposed so that it may be pushed into or upon this, or be connected therewith in another way. 7

Having now particularly described and ascertained the nature of this invention, and in what manner it is to be performed, I declare that what I claim is A movement-cure machine consisting of a handle, a driving-shaft g, within this handle and supporting a cam or eccentric h, and a shell or frame is, surrounding such cam or eccentric and having at its inner side two parallel faces between which the cam or eccentric moves, thus imparting to the shell or frame and to the contact part 0, connected therewith, the desired oscillating or shaking motion, all substantially as set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

CARL HARALD LIEDBECK.
